Description

BACKGROUND OF THE INVENTION
• 1. Field of the Invention[0001]
• The present invention relates to connectors. More particularly, the present invention relates to a storage peripheral having a robust printed circuit board (PCB) connector configured in accordance with a Serial Advanced Technology Attachment (SATA) standard.[0002]
• 2. Description of the Prior Art and Related Information[0003]
• Today, computers are routinely used both at work and in the home. Computers advantageously enable file sharing, the creation of electronic documents, the use of application specific software, and electronic commerce through the Internet and other computer networks. Typically, each computer has a storage peripheral. For example, the most common type of storage peripheral is a rotating media storage device (RMSD), such as a disk drive (e.g. a hard disk drive). However, other types of storage peripherals such as solid-state disk drive emulators utilizing flash memory are becoming increasingly common.[0004]
• Disk drives are typically connected to a host computer through a host interface connector for the transfer of commands, status and data. The host computer accesses the disk drive and reads data from the disk drive and/or saves data to the disk drive. The disk drive is typically connected to the host computer via a cable and a cable connector that connects to a PCB connector of the disk drive. For compatibility, the connectors and interface protocol are standardized. Accordingly, the cable, cable connector, and PCB connector must comply with the same interface standard. There are several disk drive interface standards, e.g., Advanced Technology Attachment (ATA) and Small Computer System Interface (SCSI) that have become common in the last decade.[0005]
• However, disk drives are now being designed to comply with a newer standard, generally referred to as the Serial Advanced Technology Attachment (SATA) standard, which is the standard presently favored for newer computers. The SATA standard is being promulgated by the Serial ATA Working Group and is specifically referred to as the Serial ATA: High Speed Serialized AT Attachment specification or Serial ATA standard 1.0. The SATA specification defines various general standards for SATA compliant cable connectors, SATA compliant cables, and SATA compliant PCB connectors that mount to a printed circuit board (PCB).[0006]
• The SATA PCB connector defined in the SATA specification basically specifies an insulated housing, a first blade connector for supporting an electrical contact arrangement configured for data signals, a second blade connector for supporting an electrical contact arrangement configured for power signals, and two board locks fixed to the housing for attaching the PCB connector to a PCB. Further, the SATA PCB connector defined in the SATA specification sets forth that the housing includes a pair of opposed guide slots in each one of two opposite side walls of the housing that define a cable connector receiving area. The pair of opposed guide slots aid in guiding cable and back-plane connectors to mate with a blade connector.[0007]
• Unfortunately, the blade connectors specified by the SATA standard are prone to mechanical failure when utilizing presently manufactured SATA compliant cable connectors and PCB connectors. Oftentimes, the blade connector of a SATA PCB connector breaks when a SATA cable connector is mated to it. This is because mating SATA cable connectors are not suitably constrained by the housing of the SATA PCB connector. Furthermore, the respective electrical contact arrangements for power and data signals, as specified by the SATA standard, may not adequately ensure that electrostatic discharge (ESD) will be consistently discharged with the first mate ground contact.[0008]

DETAILED DESCRIPTION
• With reference to FIG. 1A, FIG. 1A shows a block diagram of a system including a[0052]host computer12 connected to a storage peripheral8, in which embodiments of the invention may be practiced. The storage peripheral8 comprises acontroller26 having a Serial ATA (SATA) interface (not shown) connected to aSATA PCB connector24. The storage peripheral8 further includes asemiconductor memory28 for data storage and retrieval. Thecontroller26,semiconductor memory28, andSATA PCB connector24 are preferably mounted on a printed circuit board (PCB)13. The storage peripheral8 is connectable to ahost computer12 for receiving commands and data over aSATA cable70 having aSATA cable connector22.
• In one embodiment, storage peripheral[0053]8 may emulate a disk drive while communicating with thehost computer12 using a SATA protocol.Semiconductor memory28 may be a Flash memory system for providing non-volatile storage. In another embodiment,semiconductor memory28 may be a large DRAM array suitable for caching data in a high performance system.
• With reference to FIG. 1B, FIG. 1B shows a block diagram of a system including a[0054]host computer12′ connected to adisk drive10, in which embodiments of the invention may be practiced. In this embodiment, thedisk drive10 acts as the storage peripheral. Thedisk drive10 includes a head disk assembly (HDA)17 having a disk18 and atransducer head20 actuated radially over the disk. Thedisk drive10 further includes a disk control system25, which may include a SATA interface (not shown), and a serial ATA (SATA)PCB connector24′. The disk control system25 responds to disk-drive commands and accesses data storage locations on the disk18 through thetransducer head20. TheSATA PCB connector24′ couples the disk control system25 to thehost computer12′ when thedisk drive10 is connected to thehost computer12′ via theSATA cable70′ and theSATA cable connector22′.
• The[0055]HDA17 ofdisk drive10 further includes aspindle motor52 for rotating the disk18 and a voice coil motor (VCM)54 for actuating thetransducer head20 radially over the disk18. A servo controller56 generates the appropriate control signals applied to thespindle motor52 and theVCM54 in response to commands received from the disk control system25. During a write operation the disk control system25 transmits user data received from thehost computer12′ to a read/write channel58. The read/write channel58 performs appropriate encoding of the user data to generate write data60 written to the disk18. The write data60 modulates the operation of apreamp62 to generate a write signal64_iapplied to thehead20 in order to write magnetic transitions onto the surface of the disk18. During a read operation, thehead20 detects the magnetic transitions representing the recorded data to generate a read signal66, which is amplified by thepreamp62 to generate a read signal68 applied to the read/write channel58. The read/write channel58 demodulates the read signal68 into user data transmitted to thehost computer12′ via disk control system25 after correcting errors.
• The[0056]disk drive10 communicates with thehost computer12′ over aSATA cable70′ that includes aSATA cable connector22′ connected to theSATA PCB connector24′ using a communication protocol defined by an industry standard such as the Serial ATA standard 1.0. In another embodiment, the disk drive may communicate with the host computer using an industry standard known as Serial Attached SCSI (SAS), which contemplates using cabling and circuitry originally defined in the SATA standard.
• The disk[0057]18,spindle motor52,VCM54,preamp62, and related hardware may be integrated into theHDA17. The disk control system25,SATA PCB connector24′,semiconductor memory28′, servo controller56, read/write channel58, and related electronics may be mounted on a printed circuit board (PCB)13′. The disk control system25 generally includes circuitry and processors that control theHDA17 and that provide an intelligent control interface between thehost computer12′ and the HDA for execution of disk-drive commands. The disk control system25 may have an internal microprocessor and nonvolatile memory for implementing the techniques of the invention. Thesemiconductor memory28′ may have nonvolatile memory and volatile random access memory (RAM).

• For example, in this embodiment, as shown in FIGS. 2 and 3B, the first[0071]electrical contact arrangement213 of the first blade-receivingportion212 and the first shieldedcable272 may be configured for data signals in accordance with the SATA standard to mate with thefirst blade connector206 of thePCB connector24 having a second electrical contact arrangement similarly configured for data signals in accordance with the SATA standard and the thirdelectrical contact arrangement232 of the second blade-receivingportion225 and the second shieldedcable274 may be configured for power signals in accordance with the SATA standard to mate with thesecond blade connector228 of thePCB connector24 having a fourth electrical contact arrangement similarly configured for power signals in accordance with the SATA standard. Accordingly, the data blade-receivingportion212 mates with thedata blade connector206 of thePCB connector24 and the power blade-receivingportion225 mates with thepower blade connector228 of thePCB connector24, respectively.
• Looking particularly at the power blade-receiving[0072]portion225, the power blade-receivingportion225 includes a generallyrectangular housing233 for enclosing the powerelectrical contact arrangement232 configured in accordance with the SATA standard. At one end, the power blade-receivingportion225 includes an L-shapedopening235 for receipt of the corresponding L-shapedpower blade connector228 of thePCB connector24, which has a mating power electrical contact arrangement configured in accordance with the SATA standard, such that thepower blade connector228 of thePCB connector24 properly mates with the powerelectrical contact arrangement232 of the power blade-receivingportion225. At the other end, the power blade-receivingportion225 receives shieldedcable274 having a plurality of conductors configured for power signals in accordance with the SATA standard and the plurality of conductors are connected to the powerelectrical contact arrangement232 inside thehousing233 of the power blade-receivingportion225.
• Further, the power blade-receiving[0073]portion225 includes a pair of side guide rails. Afirst guide rail234 mates with the opposed guide slot217 of thehousing210 such that the power blade-receivingportion225 interlocks with thehousing210 of thecable connector22 and a second slenderrectangular guide rail236 mates with the side guide slot229 of the data blade-receivingportion212 and interlocks with the data blade-receiving portion. In this way, by the power blade-receivingportion225 interlocking with thehousing210 and the data blade-receivingportion212, anintegral cable connector22 is formed. Alternatively, in another embodiment, the data blade-receivingportion212 and the power blade-receivingportion225 may be integrally molded with thehousing210.
• Continuing with reference to FIGS. 2 and 3B, the pair of laterally-opposed[0074]guide arms220 will now be discussed. As previously described, theguide arms220 project from themating end216 of thehousing210 of thecable connector22 and are disposed outside of and are separate from the first blade-receivingportion212 and the connector-support gap230. In one embodiment, theguide arms220 are approximately rectangularly shaped as particularly shown in FIG. 3B. Further, as shown in FIG. 3B, theguide arms220 may be differently sized.
• In one embodiment each of the[0075]guide arms220 may include aconductive contact237 such as a grounding clip. As will be described in more detail later, the conductive contacts may provide pre-grounding functionality for one of the data or power blade-receiving portions or both. For example, one of theconductive contacts237 of a one of the guide arms may be coupled to a ground conductor of the first shielded cable272 (e.g. configured for data signals) and the otherconductive contact237 of the other guide arm may be coupled to a ground conductor of the second shielded cable274 (e.g. configured for power signals), as will be discussed. Various other grounding configurations for pre-grounding and the dissipation of electro-static discharge (ESD) will also be discussed.
• Also, in one embodiment, the[0076]housing210 and theguide arms220 may be made from a conductive plastic material such that thecable connector22 is conductive. For example, the plastic material may include a conductive filler material. This may be referred to as the conductive cable connector embodiment.
• With reference now to FIG. 3C, in another embodiment, the[0077]guide arms221 may be approximately oval shaped. Again, as previously described, theguide arms221 may be differently sized. Further, although not shown in FIG. 3C, each oval shapedguide arm221 may also include a conductive contact such as a grounding clip.
• Various other alternative embodiments of the previously described cable connectors are also possible. For example, as shown in FIG. 4B, in one embodiment, a[0078]cable connector448 utilized only for data signal connection is shown. Thedata cable connector448 may include ahousing452 for supporting a data blade-receivingportion212 having anelectrical contact arrangement213 configured for data signals in accordance with the SATA standard. The data blade-receivingportion212 may be integrally molded with thehousing452. Further, in this embodiment, thedata cable connector448 only includes oneguide arm220. Theguide arm220 is integrally formed with thehousing452 and projects from the mating end of the housing and is disposed outside of and is separate from the data blade-receivingportion212. The guide arm includes aconductive contact237, such as a grounding clip. Alternatively, as previously discussed, thehousing452 and theguide arm220 may be made from a conductive plastic material.
• The data[0079]electrical contact arrangement213 of the data blade-receivingportion212 is configured to mate with thedata blade connector206 of thePCB connector24 having an electrical contact arrangement also configured for data signals in accordance with the SATA standard. Further, a shieldedcable272 having a plurality of conductors configured for data signals in accordance with the SATA standard is coupled to the data blade-receivingportion212 and the plurality of conductors are connected to the dataelectrical contact arrangement213 of the data blade-receivingportion212 inside the data blade-receiving portion. As previously discussed, theconductive contact237 of theguide arm220 may be coupled to a ground conductor of the shielded data cable272 (e.g. configured for data signals) for pre-grounding. Therectangular guide arm220 is suitably formed for receipt by a guide arm receiving cavity of thePCB connector24, as will be discussed. Also, the SATA standard utilized may be a SAS standard.
• Further, the[0080]housing452 may include aside guide slot454 for mating with a rectangular guide rail of another separate power cable connector, as will be discussed.
• Also, with reference to FIG. 4C, an alternative embodiment of the[0081]data cable connector448 is shown. In this embodiment, thedata cable connector448 includes asecond guide arm458 that is shaped as an elongated tongue. The second elongatedtongue guide arm458 is suitably formed for receipt by a guide arm receiving cavity of thePCB connector24 that is shaped as elongated slot, as will be discussed.
• Another alternative embodiment of the previously described cable connectors is shown in FIG. 4D. FIG. 4D shows a[0082]cable connector460 that is utilized only for power signal connection. Thepower cable connector460 may include ahousing462 for supporting a power blade-receivingportion225 having anelectrical contact arrangement232 configured for power signals in accordance with the SATA standard. The power blade-receivingportion225 may be integrally molded with thehousing462. Further, in this embodiment, thepower cable connector460 only includes oneguide arm220. Theguide arm220 is integrally formed with thehousing462 and projects from the mating end of the housing and is disposed outside of and is separate from the power blade-receivingportion225. The guide arm includes aconductive contact237, such as a grounding clip. Alternatively, as previously discussed, thehousing462 and theguide arm220 may be made from a conductive plastic material.
• The power[0083]electrical contact arrangement232 of the power blade-receivingportion225 is configured to mate with thepower blade connector228 of thePCB connector24 having an electrical contact arrangement also configured for power signals in accordance with the SATA standard. Further, a shieldedcable274 having a plurality of conductors configured for power signals in accordance with the SATA standard is coupled to the power blade-receivingportion225 and the plurality of conductors are connected to the powerelectrical contact arrangement232 of the power blade-receivingportion225 inside the power blade-receiving portion. As previously discussed, theconductive contact237 of theguide arm220 may be coupled to a ground conductor of the shielded power cable274 (e.g. configured for power signals) for pre-grounding. Therectangular guide arm220 is suitably formed for receipt by a guide arm receiving cavity of thePCB connector24, as will be discussed. Also, the SATA standard utilized may be a SAS standard.
• Further, the[0084]housing462 may include aside guide rail464 for mating withside guide slot454 of thedata cable connector448.
• Also, with reference to FIG. 4E, an alternative embodiment of the[0085]power cable connector460 is shown. In this embodiment, thepower cable connector460 includes asecond guide arm468 that is shaped as an elongated tongue. The second elongatedtongue guide arm468 is suitably formed for receipt by a guide arm receiving cavity of thePCB connector24 that is shaped as elongated slot, as will be discussed.
• An additional alternative embodiment of the previously described cable connectors is shown in FIG. 4F. FIG. 4F shows a combined[0086]cable connector480 that is utilized for both data and power signal connection and is a combination of thedata cable connector448 and thepower cable connector460, previously discussed. The combinedcable connector480 may be formed by the combination of the power anddata cable connectors460,448, previously discussed, by theside guide rail464 of the power cable connector mating with theside guide slot454 of thedata cable connector448 to form the combinedcable connector480. Alternatively, the combinedcable connector480 may be formed by the integral molding of the previously described power anddata cable connectors460,448, respectively.
• The combined[0087]cable connector480 may include ahousing482 for supporting both the data blade-receivingportion212 having anelectrical contact arrangement213 configured for data signals in accordance with the SATA standard and a power blade-receivingportion225 having anelectrical contact arrangement232 configured for power signals in accordance with the SATA standard. In this embodiment, a pair of laterally-opposedguide arms220 are integrally formed with thehousing482 and project from the mating end of the housing and are disposed outside of and are separate from both the data and power blade-receivingportions212,225. The guide arms each include aconductive contact237, such as a grounding clip. Alternatively, as previously discussed, thehousing482 and theguide arms220 may be made from a conductive plastic material.
• The data[0088]electrical contact arrangement213 of the data blade-receivingportion212 is configured to mate with thedata blade connector206 of thePCB connector24 having an electrical contact arrangement also configured for data signals in accordance with the SATA standard. Further, a shieldedcable272 having a plurality of conductors configured for data signals in accordance with the SATA standard is coupled to the data blade-receivingportion212 and the plurality of conductors are connected to the dataelectrical contact arrangement213 of the data blade-receivingportion212 inside the data blade-receiving portion. As previously discussed, theconductive contact237 of theguide arm220 may be coupled to a ground conductor of the shielded data cable272 (e.g. configured for data signals) for pre-grounding. The powerelectrical contact arrangement232 of the power blade-receivingportion225 is configured to mate with thepower blade connector228 of thePCB connector24 having an electrical contact arrangement also configured for power signals in accordance with the SATA standard. Further, a shieldedcable274 having a plurality of conductors configured for power signals in accordance with the SATA standard is coupled to the power blade-receivingportion225 and the plurality of conductors are connected to the powerelectrical contact arrangement232 of the power blade-receivingportion225 inside the power blade-receiving portion. As previously discussed, theconductive contact237 of theguide arm220 may be coupled to a ground conductor of the shielded power cable274 (e.g. configured for power signals) for pre-grounding.
• The[0089]rectangular guide arms220 are suitably formed for receipt by guide arm receiving cavities of thePCB connector24, as will be discussed. Also, the SATA standard utilized may be a SAS standard. Further, in this embodiment, the combinedcable connector480 includes asecond guide arm488 that is shaped as an elongated tongue. The second elongatedtongue guide arm488 is suitably formed for receipt by a guide arm receiving cavity of thePCB connector24 that is shaped as elongated slot, as will be discussed.
• With reference now to FIG. 5A in conjunction with FIG. 2, one embodiment of the[0090]PCB connector24 will now be described in detail. FIG. 5A shows a more detailed perspective view of thePCB connector24 of FIG. 2. As shown in FIG. 2, thePCB connector24 is mounted to a printed circuit board (PCB)13. Mountingbrackets280 of thePCB connector24 support thePCB13 and mountingposts281 extend from the mountingbrackets280 via through-holes of the PCB creating an interference fit to secure thePCB connector24 to thePCB13. Further, as will be discussed many pins of the various connectors are also fixed to thePCB13 further securing thePCB connector24 to thePCB13.
• In one embodiment, the[0091]PCB connector24 includes ahousing270 having aSATA section265, a legacy Integrated Drive Electronics (IDE)power section receptacle266, and auser section receptacle268. In other embodiments of thePCB connector24, thehousing270 of thePCB connector24 may only include theSATA section265 and the legacy IDEpower section receptacle266 and theuser section receptacle268 may not be present. Particularly, looking at theSATA section265, thePCB connector24 includes afirst blade connector206 for supporting a firstelectrical contact arrangement209 in accordance with a SATA standard, asecond blade connector228 for supporting a second electrical contact arrangement231 in accordance with the SATA standard, and thehousing270 encloses the first and second blade connectors and the supported electrical contact arrangements. As should be appreciated, the electrical contacts of the electrical contact arrangements of theblade connectors206 and228 are mounted to thePCB13 via through-holes of thePCB13, for example. Alternatively, other methods of mounting the electrical contacts could be used, such as surface mount technologies.
• In one embodiment, the[0092]housing270 includes a pair ofopposed guide slots271 in each one of two opposite sidewalls of thehousing270 that define a cableconnector receiving area252 around the first andsecond blade connectors206 and228 for the receipt of at least one cable connector, respectively. The cableconnector receiving area252 is in accordance with the SATA standard. In one embodiment, the firstelectrical contact arrangement209 of the first L-shapedblade connector206 is configured for data signals in accordance with the SATA standard and a second electrical contact arrangement231 of the second L-shapedblade connector228 is configured for power signals in accordance with the SATA standard.
• However, above and beyond the cable[0093]connector receiving area252 as defined in accordance with the SATA standard, thehousing270 of thePCB connector24 includes at least one guidearm receiving cavity254 that is integrally formed with thehousing270 and that is disposed outside of the cableconnector receiving area252. In one embodiment, thehousing270 includes a pair of laterally-opposed guidearm receiving cavities254 that are integrally formed with thehousing270 and that are disposed outside the cableconnector receiving area252. The guidearm receiving cavities254 are adapted for the receipt of theguide arms220 from themating cable connector22.
• Further, in other embodiments, the guide[0094]arm receiving cavities254 are adapted for the receipt ofguide arms220 from the other alternative embodiments of themating cable connector22 such as power signal onlycable connector422, data signal onlycable connector448, power signal onlysable connector460, and combined data and powersignal cable connector480. In the cases of power signal onlycable connector422 and combined data and powersignal cable connector480, these connectors both have two laterally-opposed guide arms both of which mate to the guidearm receiving cavities254. In the cases of the data signal onlycable connector448 and power signal onlycable connector460, these connectors each have only one guide arm for mating with one of the respective guidearm receiving cavities254.
• In one embodiment, the guide[0095]arm receiving cavities254 are approximately rectangularly shaped and may be differently sized, as particularly shown in FIG. 5A. With brief reference to FIG. 5B, in another embodiment, the guidearm receiving cavities354 may be approximately oval shaped and may also be differently sized. Further with brief reference to FIG. 5C, thehousing270 of thePCB connector24 may further have an elongatedslot292 for the receipt of thesecond guide arms458,468, and488 of the data signal onlycable connector448, the power signal onlycable connector460, and the combined data and powersignal cable connector480, respectively, all of which are shaped as elongated tongues, as previously discussed.
• Returning to FIGS. 2 and 5A, the[0096]housing270 further includes substantially thickened strengtheningwalls260 disposed between the cableconnector receiving area252 and the guidearm receiving cavities254 making thePCB connector24 very robust.
• Accordingly, above and beyond presently manufactured cable connectors that mate to the SATA standards defined cable connector receiving area of presently manufactured PCB connectors, embodiments of the present invention relate to a more robust SATA[0097]compliant cable connector22 and SATAcompliant PCB connector24 that avoid many of the breakage problems associated with these present devices. This further applies to the other disclosed alternative embodiments ofcable connector22 such as power signal onlycable connector422, data signal onlycable connector448, power signal onlycable connector460, and combined data and powersignal cable connector480. With the embodiments of present invention, one or both of the data blade-receivingportion212 and/or the power blade-receivingportion225 mate with their respectivedata blade connector206 and/orpower blade connector228 of the SATA defined cableconnector receiving area252, in which one or both ofguide rails227,234 of the data blade-receivingportion212 and/or the power blade-receivingportion225 mate with one or both of theguide slots271 of the cable connector receiving area, respectively.
• More particularly, according to embodiments of the invention, the[0098]housing210 of thecable connector22 rigidly contains one or both of the data blade-receivingportion212 and/or the power blade-receivingportion225, and when thecable connector22 is mated to thePCB connector24, the pair of laterally-opposedguide arms220 of thecable connector22 mate with the pair of laterally-opposedguide arm cavities254 of thePCB connector24 such that the blade-receivingportions212,225 of the cable connector mate with theblade connectors206,228 of the PCB connector in an aligned and firm manner such that the common problems associated with the breakage of the blade connectors is avoided. This is further applicable to the other disclosed alternative embodiments ofcable connector22 such as power signal onlycable connector422, data signal onlycable connector448, power signal onlycable connector460, and combined data and powersignal cable connector480. However, in the case of data signal onlycable connector448 and power signal onlycable connector460 only one guide arm mates with a respective guide arm receiving cavity.
• Thus, the[0099]guide arms220 mating with the guidearm receiving cavities254 align the blade-receivingportions212,225 of the various embodiments of the disclosed cable connectors with theblade connectors206,228 of thePCB connector24. Moreover, much of the forces associated with the blade-receiving portions mating to the blade connectors are transferred to theguide arms220, the guidearm receiving cavities254, and the substantially thickened strengtheningwalls260 of the strengthenedhousing270 of thePCB connector24. This further reduces the forces applied to the blade connectors to further avoid breakage.
• Also, the[0100]housing270 of thePCB connector24 may further include a legacy Integrated Drive Electronics (IDE)power section receptacle266, and auser section receptacle268. The legacy IDEpower section receptacle266 includes various legacy pins267, such as 12 V and 5 V power pins and associated ground pins that are connected to thePCB13, and that can be used for powering a storage peripheral, such as a disk drive, instead of utilizing the SATA power blade connector.
• Further, the[0101]housing270 of thePCB connector24 may further include auser section receptacle268 that includes a plurality of square pins269 that are utilized to command a storage peripheral, such as a disk drive, to operate in a plurality of different modes. In the disk drive embodiment, theuser section receptacle268 is often used in disk drive testing. The square pins269 of theuser section receptacle228 are connected to thePCB13.
• Embodiments of the present invention for the various cable connectors and the[0102]PCB connector24 also provide for pre-grounding (i.e. the dissipation of electro-static discharge (ESD)). As previously discussed, one or both of theguide arms220 of the various disclosed cable connectors may include aconductive contact237 such as a grounding clip.
• As will be described in more detail later, the[0103]grounding contacts237 of the guide arms may be coupled to ground conductors of the data and power shieldedcables272,275 connected inside of the data and power blade-receivingportions212,225, respectively, in order to effectuate various grounding configurations for pre-grounding. Further, one or both of guidearm receiving cavities254 may include a conductive surface such as a grounding tab264 (e.g. a metal grounding tab). Eachgrounding tab264 is coupled to ground on thePCB13 by a ground post263, respectively. Also, it should be appreciated that either the rectangular or oval shaped guide arm receiving cavities may include conductive surfaces for mating with a corresponding grounding contact of a corresponding rectangular or oval shaped guide arm.
• Accordingly, as an example, when the[0104]cable connector22 is mated to thePCB connector24, theconductive contacts237 of theguide arms220 will engage thegrounding tabs264 of the guidearm receiving cavities254 providing pre-grounding to either one or both of the data and/or power blade-receivingportions212,225 before they engage with the corresponding data and/orpower blade connectors206,228. This of course applies to the other disclosed alternative embodiments ofcable connector22 such as power signal onlycable connector422, data signal onlycable connector448, power signal onlycable connector460, and combined data and powersignal cable connector480. Specific examples of this, related to thecable connector22 as an example, will now be described.
• However, in an alternative embodiment, the[0105]housing210 and theguide arms220 may be made from a conductive plastic material such that thecable connector22 is conductive. Further, in one embodiment, thehousing270 of thePCB connector24 may also be made from a conductive plastic material such that thePCB connector24 is also conductive and can be grounded. In this way, when theconductive cable connector22 is mated to theconductive PCB connector24, theguide arms220 will first engage the guidearm receiving cavities254 providing pre-grounding to either one or both of the data and/or power blade-receivingportions212,225 before they engage with the corresponding data and/orpower blade connectors206,228. This also applies to the other disclosed alternative embodiments ofcable connector22 such as power signal onlycable connector422, data signal onlycable connector448, power signal onlycable connector460, and combined data and powersignal cable connector480.
• Various types of grounding configurations for pre-grounding will now be discussed. With reference now to FIG. 6A, FIG. 6A is a schematic diagram showing a pre-grounding configuration wherein both the data blade-receiving[0106]portion212 and the power blade-receivingportion225 of thecable connector22 are configured for pre-grounding to thePCB connector24. A plurality of dataSATA signal conductors602 of the data SATA shieldedcable272 are shown, which are located in the data blade-receivingportion212 and are connected to the dataelectrical contact arrangement213. Particularly, a ground conductor604 is directly coupled to a grounding contact237 (e.g. a ground clip) of one of theguide arms220 for pre-grounding (i.e. electro-static discharge (ESD)). This is shown as line606 (ESD-1). Further, a plurality of power SATA signal conductors610 of the power SATA shieldedcable274 are shown, which are located in the power blade-receivingportion225 and are connected to the powerelectrical contact arrangement232. Particularly, a ground conductor612 is directly coupled to a grounding contact237 (e.g. a ground clip) of one of theguide arms220 for pre-grounding (i.e. electro-static discharge (ESD)). This is shown as line608 (ESD-1).
• Accordingly, when the[0107]cable connector22 is mated to thePCB connector24, thegrounding contacts237 of theguide arms220 will engage thegrounding tabs264 of the guidearm receiving cavities254 providing pre-grounding to the data and power blade-receivingportions212,225 before they engage with the corresponding data andpower blade connectors206,228. Alternatively, in the conductive cable connector and PCB connector embodiment, the ground conductors may just be coupled to the guide arms to provide pre-grounding. Further, it should be appreciated that this grounding configuration for pre-grounding is also applicable to other disclosed alternative embodiments of cable connectors such as the combined data and powersignal cable connector480.
• With reference now to FIG. 6B, FIG. 6B is a schematic diagram showing a pre-grounding configuration wherein the data blade-receiving portion is not present and the power blade-receiving[0108]portion225 of thecable connector22 is configured for pre-grounding to thePCB connector24. A plurality of power SATA signal conductors610 of the power SATA shieldedcable274 are shown, which are located in the power blade-receivingportion225 and are connected to the powerelectrical contact arrangement232. Particularly, a first ground conductor611 is directly coupled to a grounding contact237 (e.g. a ground clip) of one of theguide arms220 for pre-grounding (i.e. electro-static discharge (ESD)), which is shown as line612 (ESD-1). Further, a second ground conductor613 is directly coupled to a grounding contact237 (e.g. a ground clip) of one of theguide arms220 for pre-grounding (i.e. electro-static discharge (ESD)), which is shown as line614 (ESD-2). Accordingly, when thecable connector22 is mated to thePCB connector24, thegrounding contacts237 of theguide arms220 will engage thegrounding tabs264 of the guidearm receiving cavities254 providing pre-grounding for the power blade-receivingportion225 before it engages with the correspondingpower blade connector228. Alternatively, in the conductive cable connector and PCB connector embodiment, the ground conductors may just be coupled to the guide arms to provide pre-grounding. Further, it should be appreciated that this grounding configuration for pre-grounding is also applicable to other disclosed alternative embodiments of cable connectors such as the power signal onlycable connector422 and the power signal onlycable connector460.
• Looking now at FIG. 6C, FIG. 6C is a schematic diagram showing a pre-grounding configuration wherein the power blade-receiving portion is not present and the data blade-receiving[0109]portion212 of thecable connector22 is configured for pre-grounding to thePCB connector24. A plurality of dataSATA signal conductors602 of the data SATA shieldedcable272 are shown, which are located in the data blade-receivingportion212 and are connected to the dataelectrical contact arrangement213. Particularly, a first ground conductor621 is directly coupled to a grounding contact237 (e.g. a ground clip) of one of theguide arms220 for pre-grounding (i.e. electro-static discharge (ESD)), which is shown as line622 (ESD-1). Further, a second ground conductor623 is directly coupled to a grounding contact237 (e.g. a ground clip) of one of theguide arms220 for pre-grounding (i.e. electro-static discharge (ESD)), which is shown as line624 (ESD-2). Accordingly, when thecable connector22 is mated to thePCB connector24, thegrounding contacts237 of theguide arms220 will engage thegrounding tabs264 of the guidearm receiving cavities254 providing pre-grounding for the data blade-receivingportion225 before it engages with the correspondingdata blade connector206. Alternatively, in the conductive cable connector and PCB connector embodiment, the ground conductors may just be coupled to the guide arms to provide pre-grounding. Further, it should be appreciated that this grounding configuration for pre-grounding is also applicable to other disclosed alternative embodiments of cable connectors such as the data signal onlycable connector448.
• Turning now to FIG. 6D, FIG. 6D shows the layout of the data and power signal contacts of the data and[0110]power blade connectors206,228 of thePCB connector24 onto thePCB13 and furthershows grounding tabs264 of the guidearm receiving cavities254 coupled to ground onPCB13. It should be appreciated that the groundingtabs264 could also be coupled to a ground at another location. For example, in the disk drive embodiment, the grounding tabs could be coupled to the grounded chassis of the disk drive.
• It should be appreciated by those skilled in the art that although embodiments of the invention for cable connectors have been presented having only one data blade-receiving portion, only one power blade-receiving portion, and only one data and one power blade-receiving portion that a wide variety of cable connectors having multiple types of blade-receiving portions such as: multiple data blade-receiving portions, multiple power blade-receiving portions, and multiple data and power blade-receiving portions, as well as other types of blade-receiving portions are deemed to lie within the spirit and scope of the invention.[0111]
• It should further be appreciated by those skilled in the art that although embodiments of the invention for cable connectors and PCB connectors have been illustrated for use with storage peripherals, such as disk drives, utilizing a SATA standard, such as the Serial ATA: High Speed Serialized AT Attachment standard or the Serial Attached Small Computer System Interface (SAS) standard, that numerous alternative types of cable connectors and PCB connectors for various types of electronic devices utilizing differing types standards are deemed to lie within the spirit and scope of the invention.[0112]
